Hashing

The following functions perform hashing.

The server supports insecure hashing methods such as MD4, MD5 and SHA1. These functions are here for historical compatibility and completeness. They should not be used.

All of the hash functions take arbitrary data, and return binary data as octets.

List of Hash Functions

The following hashes are supported:

Table 1. Hash/digest functions
Function	Description
%hash.blake2b_512	BLAKE2b-512
%hash.blake2s_256	BLAKE2s-256
%hash.md4	MD4
%hash.md5	MD5
%hash.sha1	SHA1
%hash.sha224	SHA224
%hash.sha256	SHA256
%hash.sha384	SHA384
%hash.sha512	SHA512
%hash.sha2_224	SHA2-224
%hash.sha2_256	SHA2-256
%hash.sha2_384	SHA2-384
%hash.sha2_512	SHA2-512
%hash.sha3_224	SHA3-224
%hash.sha3_256	SHA3-256
%hash.sha3_384	SHA3-384
%hash.sha3_512	SHA3-512

Example

User-Name := "Caipirinha"

reply += {
    Reply-Message = "The md5 of %{User-Name} in octal is %hash.md5(User-Name)"
    Reply-Message = "The md5 of %{User-Name} in hex is %hex(%hash.md5(User-Name))"
}

Output

The md5 of Caipirinha in octal is \024\204\013md||\230\243\3472\3703\330n\251
The md5 of Caipirinha in hex is 14840b6d647c7c98a3e732f833d86ea9
